cgltf VS computer-graphics-from-scratch

If you want to go all the way, https://learnopengl.com/ is a favorite around here. You could build a glTF viewer from scratch starting from that tutorial and https://github.com/jkuhlmann/cgltf and eventually building towards https://google.github.io/filament/Filament.html or whatever wacky artsy direction you like.

Use https://github.com/jkuhlmann/cgltf to parse the files. https://github.com/ocornut/imgui for your UI. Maybe https://www.libsdl.org/ just to set up a window, handle mouse clicks and initialize the GL context in that window.

Use glTF and https://github.com/jkuhlmann/cgltf Or, looks like you are using C#, so https://github.com/vpenades/SharpGLTF

Do you really have to use fbx? An open format like gltf is better supported, and there are bazillions loaders(I use cgltf without any issues, which is also used by raylib, Unigine and bgfx). It's also a perfect fit for OpenGL.

I recently discovered this pattern in cgltf (https://github.com/jkuhlmann/cgltf), and I agree, it makes deployment so much nicer.

Use https://github.com/jkuhlmann/cgltf It’s the most popular loader.

It's easy to generate a BVH for a generated triangle set (like a fractal pyramid or a dense cube). But, quickly generating a high quality BVH for a loaded model requires some research. Use https://github.com/jkuhlmann/cgltf to load models.

Write a simple glTF viewer in OpenGL. This is a throw-away warm-up. So, don't fret over the code. Don't do anything complicated. Shoot for a simple, forward renderer for a simple, animated character with trivial Phong lighting, diffuse map, normal map and a basic directional shadow map. Use OpenGL ES 3.0/GL 4.3 API with no crazy features. Don't worry about performance. Use https://github.com/jkuhlmann/cgltf to load the files. KTX is a great container for textures.

I’m getting started too in graphics programming (web developer here) and I’ve started with the Raytracing in One Week-end, I find it to be great (I use ChatGPT along the tutorial to exchange and ask questions when I struggle). Other than that I also bought the OpenGL bible book and the book Computer Graphics from Scratch that you can both find on Amazon, they’re really great.

Computer Graphics from Scratch is fully available for free on the website, if you want to check it out first: https://gabrielgambetta.com/computer-graphics-from-scratch

It may be a bit basic compared to Abrash's but https://gabrielgambetta.com/computer-graphics-from-scratch/

Computer Graphics From Scratch is my favorite introduction to the subject. It assumes less about the reader than something like the "In A Weekend" series.

This one: https://news.ycombinator.com/item?id=19584921 And wasn't even my post!

A long time ago I found myself teaching Computer Graphics at my alma mater. Over the following years my approach to the subject evolved, and I really got the hang of it. After I stopped teaching, I took my notes, handouts and slides, and made them into a series of articles that I put on my website, where they remained in relative obscurity. Hacker News managed to find it every once in a while, and it was generally well received, but nothing came out of this. Until April 2019, when that post made the HN front page again, except this time it caught the attention of an editor in No Starch Press.

Long story short, my materials are now a book, Computer Graphics from Scratch, sold by No Starch Press [0], and also available for free on my website [1].

This genuinely wouldn’t have happened without your support. THANK YOU, HN community :)
